One of the topics that has been something we've been waiting to see about The Old Republic
is how team battles will happen. Grouping is one of the biggest aspects that bring people into a MMO, and TOR is approaching it through what they're calling Flashpoints. Flashpoints are areas of the galaxy where a single Jedi or Mandalorean isn't enough to to quell the problem, so players are forced to team up in order to fight their way through it. A few flashpoints have been announced so far, but there will likely be more.
